The hydrometer sinks deeper in low-density liquids such as kerosene, gasoline, and alcohol, and less deep in high-density liquids such as brine, milk, and acids. It is usual for hydrometers to be used with dense liquids to have the mark 1.000 (for water) near the top of the stem, and those for use with lighter liquids to have 1.000 near the bottom.
The Fahrenheit hydrometer is a device used to measure the density of a liquid. It was invented by Daniel Gabriel Fahrenheit (1686–1736), better known for his work in thermometry . The Nicholson hydrometer , after William Nicholson (1753-1815), is similar in design, but instead of a weighted bulb at the bottom there is a small container ...
Another type of hydrometer is the electronic Oscillating Body hydrometer which determines the density of a small sample drawn into a glass tube mounted on an oscillating mechanism. The difference in frequency between the test sample and a reference sample of distilled water is a measure of the density of the sample, which is displayed digitally.

Hydrostatic bubbles, also known as philosophical bubbles, gravity beads, aerometrical beads and hydrometer beads, are a type of hydrometer invented in 1757 by Alexander Wilson of Glasgow. [1] The design was subsequently improved and patented by the glassblower and instrument maker Isabella Lovi [ 2 ] of Edinburgh in 1805. [ 3 ]
